Collection Method: clinical testing

The c.547A>G (p.I183V) alteration is located in exon 5 (coding exon 4) of the RAD54L2 gene. This alteration results from a A to G substitution at nucleotide position 547, causing the isoleucine (I) at amino acid position 183 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
